It should be clarified that the slight cost increase is not a blocker.

The transfer process was straightforward enough:

Binero

1. Follow the links: Domäner → Redigera → Överföring
2. Click "Generera" and copy the authentication code.

Loopia

1. Click the domain name in the list.
2. Click "Flytta domänen till Loopia".
3. Fill in the authentication code and click "Genomför transfer".

Great! Please go ahead and move the rest of them as soon as possible.

First domain, wikimania.se, has been transferred (T215519) and everything seems to work.

There are a few additional steps:

• If there are settings, such as redirection, in Binero, these should be copied. They can be found under "Webbplatser" in the menu. You can then remove the site by clicking the X.
• After clicking "Flytta domänen till Loopia" there's another link "Transfer av domännamn"
• After the transfer, Loopia gives a warning about name servers needing to be updated. This can be done in a few clicks by following the instructions.

Also, to initially add domains to Loopia:

1. Köpa eller lägga till domännamn → Lägg till befintligt domännamn
2. Add domain names
3. Click "Lägg till domännamn"
4. When done, you will see a list of the newly added domains

All sites except wikipedia.se have now been transferred. There are still a few issues remaining, which may be of the kind that there are still things going on behind the scenes. I'll give it a few hours and contact support if they remain.

The following sites don't redirect properly and gives "Server Not Found"

• qrpedia.se
• wikimediacommons.se
• wikispecies.se
• wikiversity.se

The following won't change name servers, claiming that the domain name hasn't been activated

• fri-kunskap.nu
• frikunskap.nu

There was one more with this issue (wikiversity.se) that it worked for just now.

As for wikipedia.se, Binero claims that it redirects to http://sv.wikipedia.org, which is just not true. I'll have to dig around a bit to figure out what's actually going on here.

I tried parking wikipedia.se at Binero to verify that that config isn't in effect.

These are now working.

The issues with the .nu domains were solved by a quick call to Loopia's support.

All domains have been moved over and there's nothing left at Binero, as far as I can see.
